To go with Potters for Peace recommendations to make the ceramic filters in a more sexy design, I would want to work towards the western world, as a research for the design.

Water filters for personal use is very expensive (from 200 euros and up) and not made in very sustainable materials. To make a new design on the ceramic water filters would be a cheaper and more environmental alternative for home use.

       

This could for example come at use in homes that have a well that doesn’t have clean water, or in boats, where there is a risk of the water in the tank being contaminated.
